Visual Basic Code Example

  1. Insert a Visual Basic module into a new Microsoft Excel workbook.
  2. Create a reference to the Microsoft DAO object library. In Microsoft Excel 97 the DAO library will be version 3.5. In Microsoft Excel 7.0 the DAO library will be version 3.0.
  3. Type the following code into the module sheet:
        ' This code assumes you have Microsoft Access 7.0 installed and have
       ' the Northwind.mdb sample database installed in the default
       ' location.
    
       Sub CreateRecordSet()
    
         Dim oldDbName As String
         Dim wspDefault As Workspace
         Dim dbsNorthwind As Database
         Dim strSQL As String
         Dim rstFromQuery As Recordset
    
         'Set the path to the database
         oldDbName = "C:\Msoffice\access\samples\Northwind.mdb"
    
         'Create a default workspace Object
         Set wspDefault = DBEngine.Workspaces(0)
    
         'Create a Database object
         Set dbsNorthwind = wspDefault.OpenDatabase(oldDbName)
    
         'The SQL statement
         strSQL = "SELECT Employees.LastName, Employees.FirstName, " & _
            "Employees.Country FROM Employees Employees " & _
            "WHERE (Employees.Country='USA')"
    
         'Create a Snapshot Type Recordset from the SQL query
         Set _
         rstFromQuery = dbsNorthwind.OpenRecordset(strSQL,dbOpenSnapshot)
    
         'Show the number of fields returned
         MsgBox "there are " & rstFromQuery.Fields.Count & _
         " fields that were returned"
    
         'Move to the last record in the recordset
         rstFromQuery.MoveLast
    
         'Show the number of records returned
         MsgBox "there are " & rstFromQuery.RecordCount & _
         " records that were returned"
    
      End Sub
